Jenni "JWoww" Farley has never been shy about voicing her opinions, as Bristol Palin learned firsthand Thursday.

After Palin, 21, wrote a heated blog post about President Barack Obama's recent support of same-sex marriage, Farley, 26, dissed the politician's daughter via Twitter.

"Bristol should keep her uneducated, ignorant mouth shut. If you're living in the past you wouldn't have a kid without marriage. Hypocrite. It's 2012!" Farley wrote. "My best friend will get married one day and not just have civil union with his man. Stop hating people."

During his interview with ABC News' Robin Roberts, Obama explained how his daughters Malia, 13, and Sasha, 10, inspired him to think more seriously about the topic of same-sex marriage.

"Malia and Sasha, they have friends whose parents are same-sex couples," Obama said. "There have been times where Michelle and I have been sitting around the dinner table and we're talking about their friends and their parents and Malia and Sasha, it wouldn't dawn on them that somehow their friends' parents would be treated differently. It doesn't make sense to them, and frankly, that's the kind of thing that prompts a change in perspective."

In her blog post, Palin griped that Obama, 50, "made a massive change in a policy position that could affect the entire nation after consulting with his teenage daughters."

Palin argued that "in general, kids do better growing up in a mother/father home" and said that "in this case, it would've been helpful for him to explain to Malia and Sasha that while her friends parents are no doubt lovely people, that's not a reason to change thousands of years of thinking about marriage."

The single mom continued: "I guess we can be glad that Malia and Sasha aren't younger, or perhaps today's press conference might have been about appointing Dora the Explorer as Attorney General because of her success in stopping Swiper the Fox."

"Sometimes dads should lead their family in the right ways of thinking. In this case, it would've been nice if the President would've been an actual leader and helped shape their thoughts instead of merely reflecting what many teenagers think after one too many episodes of Glee."
